Here is my first post on the rctech forum =)

I currently fried my old reventon pro esc, but luckily got hold of a similar reventon pro esc. I say similar because it's not exactly the same, but both are reventon pro's. I did notice small differences between the two. First off the fan mounted on my old esc didn't fit the new esc, the new esc had mounting holes for a larger fan.
Do anybody know if they made changes to the esc during it's production?

First pack testing the esc in my 2wd buggy I instantly noticed a different "hum" from the motor. Also the trigger felt smoother, I really liked that, bud the brakes where weaker compared to my now fried reventon.

I tried the stock v20 firmware (the one focused on brakes), it did do some good things but it had cogging at low rpm's.
I then read on petitrc that the much more fleta 4 firmware would be better, tried that aswell but stil had low speed cogging and even spikes in rpm in midrange rpm's.

I would like you to share your experience with firmwares on this esc.
Any recommendation wold be appreciated.
Also why would there be such differences in performance for the brakes? Different fet's maybe?
